For 2012, the Sahara pant is almost one size smaller than the 2010 Sahara pant. This is the waist measurement. My 2010 Sahara pants, bought one size larger than normal because they were a great closeout deal, were so large that I could not keep them up. I ended up selling them to a larger friend.I just got a new 2012 pair of Sahara pants as part of my club's "worker reward gear", and my normal size was almost too tight to get the waist fastened. (Many of the club members exchanged their Sahara pants for a larger size.)Othere than the sizing, these pants are maybe even better than previous years Saharas, just cut a bit smaller.
